Unfortunately I would agree.
Gary you mentioned that you drove it about 50 miles before it started acting up. When the ecm's fail they will start out working fine until they get hot. You can try unbolting the ecm from the side of the block, and just hook up a ground wire to it. If it drives farther before it fails, then you found your problem.
The buzzing is a puzzle. Not much to buzz under the valve cover of a vp truck. Are you sure it's not the grid heater relays?
